Thanks, I'm still a reader!
Are you planning to cover messagebox-like stuff (i.e. gtkdialog.. 
i guess?)

Excellent. Thanks for letting me know.

 gtkdialog.. i guess?)


Yes. Right after this series on menus, I start on Dialogs. The 
first couple of those are already in the grist mill (HelpDialog, 
FileChooserDialog) giving that series five articles so far. But 
I'll put MessageDialog next on the list which means it'll be 
posted on May 31st.

I'm asking because there was discussion elsewhere on the net 
about another programming language where a [gtk] messagebox title 
was too long so the text could not be read completely because the 
messagebox sized itself to the shorter text in the content area. 
They said it's an OS limitation (meaning gtk standard dialogs). 
It also seems dialogs are not user-resizable by default, which 
seems strange to me. So I thought to roll my own dialog, but 
didn't get to it yet.
I also wonder why I often encounter gtk apps/windows that are 
unresizable, but still have the resize-icon cursor when hovering 
the bottom-right window edge, which when used moves the window 
instead.

Because the Dialog class inherits from Window, you can size it 
with setSizeRequest(). On Windows, at least. I'm not sure about 
Linux. I'm about to go out for a few hours, so perhaps you could 
test this.

That's another topic I have on my list for the dialog series.

It's because there are two flags controlling resize-ability, both 
found in generated\gtkd\gdk\c\types.d:
- a window decorations flag (GdkWMDecoration), and
- another that controls whether or not the window is allowed to 
resize (GdkWMFunction).

If the programmer turns off the resize flag, but not the 
decorator flag, well... there's your answer.

Hope that helps, number.

Yes, this work on Linux, too.

Sorry, I was unclear. By rolling my own I meant to not use a 
predefined library function MessageRequester() that exists in 
that language, but instead using gtk dialog directly which would 
be more customizable. Anyway that would only be for learning 
purposes, nothing I desperately need.

Ok, I understand. But then it seems still strange that the window 
can be moved by dragging the edge if it's only a decoration that 
is active.

Thanks for your explanations.
